MACHINE FOR TREATING VAMPS.

Application filed. October 27, 1922; Serial No. 597,382.

To all whom it may concern:

Be it known that I, HoRA'rIo S. LYNESS, a citizen of the United States, residing in Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Treating Vamps, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for operating on sheet material and is herein shown as embodied in amachine for perforating and marking vamps for shoes.

In the preparation'of uppers for boots, and shoes it is customary to mark certain parts, such as vamps and wing tips, with location marks which subsequently facilitate the presentation of said parts to a machine for performing another operation, for example, a perforating machine which applies either a row of ornamental punchings" or a cluster of ornamental punchings in the form of a medallion. Said location marks, or some of them, also serve to indicate the points of attachment of other parts such as the uppers which are subsequently united by stitching to the vamps. The marks are applied in various ways, by hand or by machine, but the operation, heretofore, has been distinct from the ornamenting operation so that for both operations, two presentations of the work have been necessary. It is an object of this invention to provide an improved machine for applying location marks to vamps or other similar blanks capable of being handled in a similar manner and for ornamenting' or otherwise operat-' ing upon them in one operation. Inthe illustrated embodiment of the invention, there is incorporated with a throat gage which locates vamps with respect to a punching machine, a pivoted marker which is moved against the centers of the throats -of the vamps to indicate. the points of attachment of the uppers. As shown, the marker is actuated yieldingly by a treadle which controls the clutch of a perforating machine. Y

Another feature of the invention relates to improvements in a throat gage by which blanks such as vamps are located or centered. Heretofore sets of pivoted gage arms with rolls at the ends have been mounted adjustably on a work support to engage the lnterior edges of the throats ofvamps to center the latter. The substantially point contact of these rolls with the thin material is apt to upset or curl the edges with a consequent lack of that precise positioning which is required for properly locating the perforations. In the illustrated improvement, two long bars arranged to lie in engagement with the interior edges of the vamps along their wholelength, are pivotally connected to the sets of gage arms and this long contact avoids upsetting the material.

In referring to the work, the term vamp has been repeatedly used throughout the specification and claims. This has been done for the sake of convenience and brevity and not in a limiting manner, it being intended to cover not only vamps inv a literal sense but wing tips and other blanks capable of being handled in a similar manner.

These and other features and advantages of the invention will appear from a consideration of the following specification and accompanying drawings in which Fig. 1 is a perspective view of the machine;

Fig. 2 is a detail View of a portion of the throat gage and the marker;

Fig- 3is a perspective view of the throat gage; p

Fig. 4 is a vertical central section of the machine;

Fig. 5 is a plan view of a portion of the machine showing a vamp in punching and marking positions;

Fig. 6 is a plan View of a modified form of the invention;

Fig. 7 is a perspective view of the parts a block 16. The block is formed on the end of a plunger 18 slidable in guides on the frame and reciprocated by toggle arms 20 actuated from the drive shaft of the machine. Any suitable one-revolution clutch, indicated generally at 22 and controlled by a spring-depressed rod 24 connected to treadle 26, may be used.

A vamp support in the form of a fiat plate projects from the punch block 12 and is preferably integral therewith. It has a circular opening 32 from which there extends toward the punch a long slot 34. Slidable on the vamp support 30 is a block 36 having a tongue guided in the slot 34 and adjustably held therein by an integral stud projecting down through the slot and threaded for the reception of a clamp nut 88.- From the sides of the block 36 there project indicators 40 for cooperation with scored lines of reference 41 on the vanrpsupport. These lines, for instance, may indicate sizes and the slide block 36 can be clamped in any desired position along the slot 34 as determined by the size. To front and rear sets of pivot pins 42 and 44 projecting upwardly from the block 36, there are pivoted front and rear sets of arms 46 and 48 confined between the block and a cover plate 50. The arms are normally pressed toward each other and toward the center of the gage by leaf springs 52 fixed to the block 36. Each set of arms is independently movable againstthe tension of the springs by cone pointed screws 54 or 56, the conical surfaces engaging the sides of the arms near their pivoted ends.

To furnish a contact of great extent along the inner edges of the vamp throats thus to avoid upsetting the thin material, the front arm on each side of the gage is connected with the rear arm on the same side by a bar 58. The rear end of each bar has a hook extending around a roll 62 on the end of the corresponding rear arm. hooked connection provides the necessary lost motion between the bar and the arm as the gage is opened and closed to fit the different sizes of Vamps. 7

Hitherto Vamps have-been provided with location marks to facilitate their presentation to a punching machine and also to in di'cate the points of attachment of other parts, the marking and perforating being carried out in two distinct operations. One such mark is frequently applied to the center of the vamp at the throat to indicate the point of attachment ofthe upper. By this invention this mark is applied during the perforating operation. Fixed to the slide block 36 is a block 64 to one end of which there is pivoted at 66 a lever 68, the forward end of which has a downwardly projecting marker in the form of a stab point70. This point normally overlies the The vamp when in marking position and the distance that the mark is to lie from the edge of the material can be regulated by an adjusting screw 74 threaded in the slide block 36 and passing through a slot 72 in the block 64. Themarker is held above the surface of the vamp support byitsrear arm 7 6 from which there projects a headed screw 78 extending into a recess of the block 64 and having a spring interposed between its headed portion and the bottom of the recess. The marker is actuated by a downward extension 82connected by a spring 84and a flexible member-86 to the threadle 26. In operation, the vamp to be treated is inserted between the punch block and the punch and around the throat gage which is firstadjusted to lit the particular size and style. Upon depression of the treadle, the marker is'pressed against the central portion of the vamp-near the edge of the throat; thereafter the spring 84 gives and continued depression of the treadle actuates the clutch 22 and starts the machine.

In Figs. 6,7 and 8 there is shown a modified 'form of marker which is automatically operated when a punch block is reciprocated towards a piece of work lying on the stripper plate of'a fixed die. At 88 is a gang punch or die which cooperates with a reciprocating punch block 90', there being a springpressed plate 92 interposedbetween these members to stripv the work from the punches. A' vamp supporting plate 54, preferably integral-with the stripper plate 92, is slit as indicated at 96 to form a spring tongue 98 which yieldably supports a throat gage and marker. A slide plate 100 is adjustably mounted on the tongue 98 and carries a be opened and closed in any desired manner to fit the throats of Vamps. This particular gageis similar to that-disclosed in Patent No. 1,448,751. granted March 20, 1923 to George Knight, Serial No. 472,709 filed. May 26, 1921, to which reference may be hadfor the details of construction not ma terial to this invention. There is a notch 104 at the center of the vamp support and pro-- jecting into this notch is a stab point or marker 106 carried on'a spring arm 108 adjustably connected to the slide plate 100 by a screw 110 passing through a slot in the arm and threaded in the plate. In this form of'the invention themark is automatically applied when the work lying on the vamp pair of gage arms 102'which may i support is depressed-by the punch block against the marker. Thetongue 98iand the associated parts are depressed into a recess of the die bythe punch. block but the forward end of the spring arm 108 strikes the dieand supports the stab point 106 for the marking operation.
